Several Samsung Galaxy devices outside of the current high-end models have begun updating to Android 4.4 KitKat, but there are still many others that have yet to see a rollout.
Sources recently shared with tech website SamMobile a list of Galaxy devices that are expected to update in the coming weeks and months, including when these updates may roll out. According to a leaked Android 4.4 update status report obtained by SamMobile, models including the Galaxy Note 2 LTE GT-N7105, Galaxy S3 LTE GT-19305 and Galaxy Note 3 Neo SM-N750 should begin receiving the new operating system in May. Additionally, it notes that the Galaxy Note 2 GT-N7100 began updating in April, which is accurate; this model received the Android 4.4 update in France on April 25. Galaxy models expected to update in June include the Galaxy S4 Mini GT-19190, Galaxy S4 Mini LTE GT-19195, Galaxy Grand 2 SM-G7102, Galaxy Mega 5.8 GT-19152 and the Galaxy Mega 6.3 GT-12900.
One model; however, has been left out of the update timeline, the Galaxy S3 GT-19300. Sources indicate that Samsung has had trouble implementing its TouchWiz apps onto the Android 4.4 KitKat software for the international Galaxy S3 model and that the update is currently canceled. It is uncertain whether this model will be revived for an Android 4.4 KitKat update in the future. As said, other Galaxy S3 models, including the LTE GT-19305 are scheduled to receive the Android 4.4 update.
Sources also indicate that Google is now testing Android 4.4.3 firmware for the Samsung Galaxy S5. There have been rumors about the impending release of Android 4.4.3 for some time; if such a build is released in the near future, it is possible that some of the Galaxy models scheduled for later releases might update to Android 4.4.3.
According to mid-April reports, Android 4.4.3 is in its “dogfooding” phase at Google, meaning it is rolling out to Google employees outside of the Android team. Devices supposedly included in dogfooding rollout are the Nexus 4, Nexus 5, Nexus 7 2012, Nexus 7 2013, and Nexus 10; Google Play Edition devices and the Moto X are also expected to rollout for Google employees.
The Android 4.4.3 update is expected to address more than three dozen bugs brought on by Android 4.4.2, including issues with the Nexus 5 camera, Bluetooth and data connection problems, and various battery draining issues.
One issue having to with battery brain caused by the Nexus 5 camera is localized within the mm-qcamera-daemon system code, which allows third-party apps (like Snapchat or Skype) access to a device’s camera. The mm-qcamera-daemon process continues to run even when those apps are closed and contributes to battery drain.
So far, Google has not indicated any plans to roll out an Android 4.4.3 update.
